UPDATE 2: No Tsunami Expected From 4.2-M Kīlauea Rift Zone QuakeApril 27, 2019, 5:36 PM HST (Updated April 27, 2019, 8:18 PM)
UPDATE 2: Magnitude-4.2 earthquake SE of Volcano, Hawaiʻi
The U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) recorded a magnitude-4.2 earthquake on Saturday, April 27, 2019, at 5:26 p.m. HST.
The earthquake was located about 12 miles SE of Volcano on the Island of Hawaiʻi at a depth of approximately 4 miles.
This earthquake is part of the continuing adjustments beneath the south flank of Kīlauea following the magnitude-6.9 earthquake that occurred on May 4, 2018.
Twenty seconds before the magnitude-4.2 earthquake, a magnitude-1.6 quake occurred deep beneath Kīlauea Volcano’s Southwest Rift Zone, causing some initial confusion about the larger earthquake’s location.
More details about the magnitude-4.2 earthquake are available at the National Earthquake Information Center website.
Weak to light shaking, with a maximum Intensity of IV on the Mercalli Intensity Scale, has been reported primarily in East Hawaiʻi, with a few reports from West Hawaiʻi.
The USGS “Did you feel it?” service received over 100 felt reports within an hour of the magnitude-4.2 earthquake.
The earthquakes have caused no detectable changes in activity at either Kīlauea or Mauna Loa volcanoes.
According to the Pacific Tsunami Warning Center (PTWC), no tsunami was generated by the earthquake.
